COLD WEATHER CARBURETION
MODIFICATIONS
All vehicles have been calibrated for - 20°C (- 4°F). They can be oper-
ated at warmer winter temperatures without problems.
CAUTION:
For colder temperatures than - 20°C (- 4°F), carbure-
tor(s) must be recalibrated to avoid engine damage. Refer to an
authorized SKI-DOO dealer.
Refer also to RIDING AT HIGH ALTITUDES in following pages.
BREAK-IN PERIOD
Engine
CAUTION:
A break-in period of 10 operating hours — 500 km
(300 miles) — is required before running the snowmobile at full
throttle.
During break-in period, maximum throttle should not exceed 3/4.
However, brief full acceleration and speed variations contribute
to a good break-in.
CAUTION:
Engine overheating, continued wide open throttle runs
and prolonged cruising without speed variations should be avoid-
ed, this can cause engine damage during the break-in period.
To assure additional protection during the initial engine break-in,
500 mL (18 imp. oz) of recommended injection oil should be added
to fuel for the first full filling of fuel tank. Have spark plugs cleaned
after engine break-in.
Belt
A new drive belt requires a break-in period of 50 km (30 miles). Avoid
strong acceleration/deceleration, pulling a load or high speed cruising.
10-Hour Inspection
As with any precision piece of mechanical equipment, we suggest
that after the first 10 hours of operation — 500 km (300 miles) — or
30 days after the purchase, whichever comes first, your snowmobile
be checked by an authorized SKI-DOO dealer. This inspection will
also give you the opportunity to discuss the unanswered questions
you may have encountered during the first hours of operation.
The 10-hour inspection is at the expense of the snowmobile owner.
